摘要
探讨了影响超声波法提取菊花中黄酮类化合物提取率的主要因素,通过正交试验法确定了最佳提取工艺:使用溶剂为60%的乙醇,在温度50℃,料液比1∶20的条件下提取10min,黄酮提取率为96%.
The optimum extraction technology of flavonoids from chrysanthemum were studied according to the orthogonal design in this paper. In comparison with the ethanol refluxing extraction technology, the results showed that the ultrasonic method was superior to the eth- anol refluxing technology. It was found that 1 ： 20 of 60% ethanol to the chrysanthemum weigh ratio was used with ultrasonic treatment lasted for 10 min at the temperature of 50℃. The average extraction rate was as high as 96 %.
